Class Overlay

java.lang.Object

haberman.rhizomatics.map.Overlay

Direct Known Subclasses:

OverlayCircle, OverlayPolygon

public class Overlay
extends java.lang.Object

This class is the root polygon which describes every markers within Rhizomatics. Computing a given amount of peels, this class becomes capable of animation. It's a solution I've found for polygons' animation, since we can't do it in mapbox (can't use AnimatedVectorDrawable, can't extend the final Polygon)...

stop_growth

private void stop_growth()

Stops the growth animation.

in

public void in()

The user location is inside.

start_growth

private void start_growth()

out

public void out(float opacity)

The user is outside.

Parameters:

opacity - The new opacity_ to set.
